This study examines the integration properties of total renewable energy production, as well as production of biofuels and biomass in the United States. To do so we use Lagrange Multiplier (LM) univariate unit root tests with up to two structural breaks. We conclude that each production series...

Agriculture has the potential to supply considerable amounts of biomass for renewable energy production from dedicated energy crops as well as from crop residues of existing production. Bioenergy production can contribute to the reduction of greenhouse gas (GHG) emissions by using ethanol and...

A computer-simulation model of the behaviour of a photovoltaic (PV) gas-turbine hybrid system, with a compressed-air store, is developed in order to evaluate its performance as well as predict the total energy-conversion efficiency and the incurred costs under various operating conditions. This...

We analyze the impacts of future scenarios of electric vehicles (EVs) on the German power system, drawing on different assumptions on the charging mode. We find that the impact on the load duration curve strongly differs between charging modes. In a fully user-driven mode, charging largely...

A flexible coupling of power and heat sectors can contribute to both renewable energy integration and decarbonization. We present a literature review of model-based analyses in this field, focusing on residential heating. We compare geographical and temporal research scopes and identify...

Although electricity supply is still dominated by fossil fuels, it is expected that renewable sources will have a much larger contribution in the future due to the need to mitigate climate change. Therefore, this paper presents a new framework for developing Future Electricity Scenarios...

Growing prosperity among its population and an inherent increasing demand for energy complicate China’s target of combating climate change, while maintaining its economic growth. This paper, therefore, describes three potential decarbonization pathways to analyze different effects for the...

This article introduces a modified simulated annealing triple-optimizer for finding the optimal energy management strategy in terms of financial gain maximization in grid-connected, storage-augmented, photovoltaics-supplied prosumer building microgrids in a variable grid price scenario. For...

Technology transfer from developed to developing countries is often problematic. Insufficient resources for operation and maintenance after project finalization are common challenges. Findings from assessments of two projects in rural Botswana and Namibia where different renewable energy...
